- Check motor operation (acceleration, deceleration and braking): accelerate to full speed direction S1, change to full
speed direction S2 and full speed direction S1 again and stop.
- Check limit switch functions: drive direction S1 slowly and check the limit switch operations. Re-check using full
speed. Repeat the same check for direction S2.
2.17.1 Functional test run for SSU
m
Note! Test run for SSU must be made without load.
- Disconnect the signal wire coming from the pulse sensor to terminal X1:51. All the SSU faults will be reseted
automatically after one second when the pulses from the pulse sensor are missing
- Drive with minimum speed. The motion must stop within set time.
- fault F63 (stall supervision) is activated
- Drive with maximum speed, the motion must stop at once
- fault F62 (Speed difference) is activated
- Reconnect the disconnected signal wire to terminal X1:51.
- Set rotary switch S1/S3 value 2 steps smaller
- Drive with maximum speed. The motion must stop after full speed is reached.
- fault F64 (Over speed) is activated
- Set rotary switch S1/S3 back to original value.
2.18 Test run with load
- Note, three loads are required:
- Nominal load (100%) for normal operation.
- Limited load for ESR (optional).
- An adequate extra load for dynamic overload testing and to test the ESR load limit.
- Make sure that movement will not cause any danger to the environment or to the crane itself.
- If the optional extended speed range (ESR) is used, check that the load limit is correctly set and hoisting with bigger
loads is prevented.
- Drive in both directions at minimum and maximum speeds.
- If the fan tube resistor unit is included, check that fan(s) starts to blow when driving down with nominal load and
continues to blow for about 4-5 minutes after stopping
2.19 Test run with overload
If an overload test has to be performed during crane commissioning, minimum frequencies should be raised for duration
of the commissioning to 20Hz. Minimum frequencies can be changed with parameters P2.2.8 and 2.2.9. After testing,
minimum frequencies should be changed back to their original values.
2.20 After the test run
- Record all parameter value changes in the parameter list.
- Make sure all remarks and setting values are recorded.
- It is recommended to store the parameter settings in file User parameters, see chapter “User parameters”.
